UNITED STATES HENRY S. DAGGETT, OF LAFAYETTE, INDIANA.

IMPROVEMENT IN ELECTRO-MAGNETIC ENGINES.

Specification forming part of Letters Patent No. 122,572, dated January9, 1872.

T 0 all whom it may concern:

Be it known that I, HENRY S. Daeen'rr, of Lafayette, in the county ofTippecanoe and State of Indiana, have invented a new and ImprovedElectric Engine; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to theaccompanying drawing forming part of this specifica tion.

Figure 1 represents a side elevation of my improved electric-engine.Fig. 2 is a vertical transverse section of the same, taken on the planeof the line 0 c, Fig. 1. Fig. 3 is a detail horizontal section of thesame, taken on the line 7t 70, Fig. 2.

Similar letters of reference indicate corre sponding parts.

This invention relates to a new arrangement of stationary magnets andvibrating conductors, and to a new combination of the same with asliding piston-rod and vibrating link movement, whereby a completeelectric-engine is produced, imparting reciprocating motion to thepiston and other suitable action to the mechanism connected therewith.

A, in the drawing, represents the frame of my electric-engine. B is arack supported by the frame A for holding a series of magnets, O (3, inrows. The magnets are horseshoes, and so placed on the rack that alltheir ends point toward a narrow passage, a, in which an arm, I),projecting from the piston-rod D travels. There are thus two sets ofmagnets, one on each side of the arm b, as shown in Figs. 2 and 3. Themagnets, constituting a vertical row in each set, are connected witheach other by a wire, there being thus as many wires, d d (1 d &c., asthere are vertical rows of magnets. Every wire (1 d connects the twoopposite rows of both sets of magnets, as shown in Fig. 2. At one endall these wires are connected with one of the conducting wires, 0, fromthe battery. At the other end they all have pendent chains, f f f, 850.The arm b of the piston-rod carries a projecting lever, E, which is atone end swiveled to the arm b, while its other end is, by a chain, 9,connected with the other conducting wire from the battery. Thepiston-rod is, by pitman It or otherwise, connected with the shaft '5,or machinery to be set in motion.

iVhen the piston or arm I) is, as seen in Fig. 1, between the first rowsof magnets and the lever E, by the chain f resting on it, connect edwith the second wire (1 the second row of magnets will be charged,causing the arm I) to be drawn by them in the direction of the arrow,shown in Fig. 1. By such motion the chain f is detached from the leverE, and the chain f brought in contact therewith, causing the third wired and the third set of magnets to be charged, and the piston to be movedahead in the same direction. At the end of the stroke the lever Estrikes afixed projecting stop, j, which causes it to turn on the armbin such manner as to resume contact with the chain last dropped, andthereby cause the charging of the magnets last passed and the reversalof motion. At the end of the opposite stroke the lever E strikes anotherstop, I, with equal effect, and causes the motion of the piston to beonce more reversed.

The magnets, it is evident, are insulated from their supporting racks.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent 1. The magnets O C, arranged in rows and connectedwith the wires (1 (l (I? d and pendcntcha-ins f f f 850., substantiallyas herein set forth and described.

2. The piston I) provided with the swivel lever E, which moves under thechains j, J, &c., and thereby produces successive connections with theseveral rows of magnets, as set forth.

3. The stops j l, affixed to the frame A, for swinging the lever E atthe end of every stroke, and thereby reversing the motion of the engine,as specified.

4. The electric-en gine, consisting of thefra-me A, rack B, magnets G 0,wires 01 d (P, &c., chains ff f, &c., piston b, lever E, and stops j Z,all combined to operate substantially as herein shown and described.

HENRY S. DAGGETT.
